Micro-Computed Tomography

The Micro-CT core facility, located at the Department of Clinical Dentistry, is available to both internal (UiB) and external users.

Computer Tomography is a non-destructive inspection technique based on differences in absorption or attenuation of X-Rays through the material. The CT-technique provides a 3-D data-set of the sample. The attenuation of X-Rays depends on the atomic number, density and thickness of the material and on the energy of the X-Ray beam. Non-destructive inspection of internal structure, tomo-density analysis, size, and volumetric measurements are possible on the 2-D as well as 3-D images.

The Skyscan 1172 is a high-resolution desktop X-ray micro-CT system for small samples.
